In a 100 watt light bulb how many volts are in it?

If it's a 100 W bulb that does not say everything about it. It could be a 12 v, 24 v, 120 v or a 230 v bulb, or other voltage. Look on the case or the packet.


The current in a 100-W bulb connected to a 120-V source is?

The apparent answer to the question would be (100 W)/(120 V) = 0.8333 A, assuming that, as a pure resistance load, the light bulb has a power factor close to 1.0.


How many amps in a 300watt bulb?

There are zero amps in a 300 watt bulb. Watts are the product of amps times volts. W = A x V. To find amperage use the equation A = W/V. If you find the voltage of the 300 watt bulb uses, divide the wattage by the voltage and it will give you the amps of a 300 watt bulb.


What power does a light bulb with 120V and 5A have?

Power= V * A so 120 V * 5 A = 600 W (J/s)


Which has the least resistance a 40Watt bulb or 200Watt bulb?

Recall power P = V2/R For a constant V, P is inversely related to the resistance of the filament. Hence 40 W bulb would have more resistance than that of 200 W bulb.


What does percent of change mean?

It is expressing a change in the value of something as a percentage of its original value. So, if the original value (V) changes to the new value (W) then the change is W - V. Then, the relative change is (W - V)/V and the percentage change is 100*(W - V)/V = 100*(W/V - 1)


Would a 40 watt light bulb use less current than a 100 watt light bulb?

Power (w) = Volts (v) * Current (I) I = P/V 100w bulb = 100/230 = 434mA 40w bulb = 40/230 = 174mA


How much amount of current does a 14 watt cfl bulb consumes?

A 240 v 14 w cfl bulb uses about 0.14 amps.


What is the amps of a 60watt bulb?

The amps times the volts equals the watts. A 120 v 60 w lamp takes ½ amp, while a 240 v 60 w lamp takes ¼ amp


What is the current that flows through a 100 w light bulb if it is connected to a 110 v source?

0.909 Amps


On a Volvo 850 Wagon what does the indicator light with the light bulb w an exclamation point mean?

it means that a bulb is burned out


How much current would flow through a 75 w bulb in a 220 v curcuit?

The formula you are looking for is I = W/E. Amps = Watts/Volts.


Can a 85 watt headlight bulb be used to replace a 45 watt fog light bulb?

To do any replacements of different bulbs you have to consider what the new current will be and if the wire size and fuse will be able to take the new current (amps). Use this formula, W = A x V or A = W/V.


What does roman numeral w mean?

There is no Roman numeral W. There is I, V, X, L, C, D and M but no W.


Which has a more resistance a 100 W bulb or a1000 W heater?

The 100W Bulb


Which draws more current a 40-w bulb or a 100-w bulb?

100


What does w v s mean?

I think it's a sports channel.


Which glows more brighter a 100 w bulb or a 75 w bulb explain?

The 100-W bulb because it transforms electrical energy at a faster rate than a dimmer bulb.


When a 100w 100v bulb is connected in series with a 40w 100v bulb and 200v supply is given what happens?

40W Bulb will spiol due to over current passing through its coilAnswerSince the 40-W lamp has a higher resistance than the 100-W lamp, the greater voltage drop will appear the 40 W lamp. As a result the 40 W lamp will be subjected to a voltage beyond its 100-V rating, and the 100-W lamp will be subjected to a voltage below its 100-V rating. Therefore, the 40-W lamp will burn much more brightly than the 100-W lamp.Incidentally, the symbols for the 'watt' and 'volt' are upper, not lower, case: W and V.


Which glows more the 100-w bulb or the 75-w bulb?

Think the 100-watt?


What is the power rating of a light bulb when 0.8 a flow through it when connected to a 120 v outlet?

The formula you are looking for is W = I x E. W = Amps x Volts.


How many lumens are in a 100 watt incandescent light bulb?

100 W tungsten incandescent (220 V): 1380 lm


What is the current in a 100 watt light bulb if the voltage is 110 V?

The formula you are looking for is I = W/E. Amps = Watts/Volts.


What is the resistance of a V W lamp is?

VW as in Volkswagen I suppose... The resistance of an incandescent(glow wire) bulb depends on the power - the wattage.


What is the voltage formula?

W= V x A or W/A=V
